SELF-CLOSING- FA'UCET OR VALVE FOR LAVATORIES OR OTHER FIXTURES.

Specification of Letters Patent.

7 Patented Dec, 29, 1908.

Application filed February 19, 1908. Serial No. 416,664.

To all whom it may concern:

Be it known that I, CARL BARR, a citizen of the United States, residing in Chicago, in the county of (look and Stateol Illinois, have invented a new and useful improvement in Self-(losing Faucets or Valves for Lavatories or other Fixtures, of which the following is a specification. Y My invention relates to self-closing faucets, cocks or other valves for lavatori'es,

sinks and other plumbing fixtures or devices.

The object of my invention is to provide a self-closing cock, faucet or valve, of a simple, e'il'icient and durable construction, which will not be required to be held open while the water or other fluid is being drawn into the lavatory or other receptacle, and which will automatically close with certainty and reliability after the )roper flow has been comeing once closed will be securely held closed owever great ma pleted, andin w ich also the valve after h be the pressure of the water or other fiuit against which the valve,

is closed.

My invention consists in the means I employ to practically accomplish this object or result; that is to say it consists in the 001m bination with the valve of the faucet, cock or other device, and the screw stem or other device for operating the valve and a spring for closing the valve or setting it to its seat, of a train of gears furnished with an escapement for controlling or regulating the movement of the train. By this combination of the valve and valve stem of the faucet, or cock with a clock movement or a time train, the period during which the valve remains open 'and the How of water through the cock continues, may be regulated as desired by simply adjusting the weight in or out on the vibrating arm of the escapement; and. after the spring closes the valve noaniount of head or pressure which the water in the supply pipe .may have, can cause the valve to open or leak as the time train effectually prevents any opening movement of the valveexcept by moving the alve stem through the operating handle or lever In the accompanying drawing forming a part of this specification, 1. have illustrated my invention as applied to an ordinary basin cock or faucet, this being one suitable embodiment ofit and serving to illustrate its principle and. mode of operation. for all other uses for which it is suitable.

In said drawing Figure 1 is a side eleva-.

tion, partly invertical central section; F igs.'

2 and 3 are horizontal sections on lines 2-2 [seat I), and a port I) closed by the 'valve 0. Any suitable form of valve may be employed; as illustrated in the drawing the valve is shown as one which closes against the pressure of water or other fluid in the suppl pipe A, and as being provided with a gas et or packing C to engage the valve seat.

The valve may be operated, or opened and closed through the agency of any suitable lever, stem, or device. As shown in the drawing the valve operating means consists of a stem D having a coarse screw d engaging screw threads b on the upper portion of the valve shell B. At its upper end the valve operating rod or stem D is provided with a knob D for turning the swn'e.

F is a clockmovement or time train, furnished with a vibrating escapenient F and a spiral spring G, secured at one end to the valve stem 1) and at the other end to the base plate F of the clock movement or time train of gears, so that the action of the spring G in closing the valve will take lace through the time train, and the time of closure be regulated bythe time escapement. The lower gear f of the time tram is loose or journaled to turn on the valve stem D, and carries the. pawl f adapted to engage a ratche f which is fast on the valve stem D, so that hen the valve stem D is turned by its handle D to open the faucet, the spiral spring G is wound up around the valve stem and can only operate to turn the same through the time train the movement of which is regulated by the escapement F.

The cscapeinciit l3 oi the time train has a vibrating arm f furnished. wit h an, adjustable l (Cd in any position weightf which may be desired by a set screw; so that the time train may be made to run mver or faster as desired to increase or diminish the period the valve remains open. ,frnv suitable term or construction, of clochw or time train mechanism may be empl ed, and it may be com osed of any desired nui'nber of internies iing gears. .The valve stein l) extends up through a suitable hole in the base plate ii of the time train, and this base plate is )revented from turning with the valve stem y a stationary bracket i i secured t he loo "with the self closing of the valve.

valve shell 3, or other suitable support, and

having erm 72- through which a guide pin or serewf" on the base plate of the time train extends, this guide pin having it sliding engagement with the bracket arm it, so that the time train may move up and down with the valve stein.

F is the cover or ease of the clock move ment or time trein, the same likewise having EtIl o ieuing through which the valve stem extends. The time train it will be seen, is mounted upon and moved with the valve stem and valve, above and outside of the Water faucet or other water delivery shell fixture, and. is irielosed hyits own case or shell l5, which is orel'erably of cylindrical form, sndquouuteo to project eliielly to the resr of the valve stem, so that it will not he in the Way or project over the lavatory or other recepteele G, into which the water is to be delivered from the Water supply pipe A through the faucet or delivery shell B. The time train controlled valve regulates the period of the Water flow, while not interfering 'l he time triiiii frame or base plate F is prevented by the bracket H and guidef from turuiiw with ?J the valve stem While permit-ting it to reciproeete up and down with the valve stem, upon whiel it is mounted. As the time train is meunted'upon the valve stem above the faucet or Water delivery device B and vulvc 4 C, and es -it is iuolosed Within its own ll,

the gears, and mechanism of the time train ere effectually protected from water and eonse uentrusting or other injury.
